Maybe we should add this to PlatformDetector and create a unit test for it? (we run on Travis which is Mono)

Guess I broke it then in 4.3.10 in #1680 :(

Any idea how to fix this? Guess we need a timer and a check if it's used.

Ps

I found a way to figure out whether there is a console/terminal available or not under mono on linux: 'Mono.Unix.Native.Syscall.isatty(0)'.
